How to remove Aeria from Tribes: Ascend

I had already gotten the game on Steam a while ago, and wanted to receive the benefits of connecting my game to Aeria Ignite. When I started the game up, I logged in with my Aeria Ignite username and pass because of the pop-up that appeared. When I got into the game, I was unable to log into my old account on Tribes and was unable to receive everything I had paid real money to get. I want to know if it is possible to remove Aeria from the game so I can use my old account again. Also, I cannot exit the popup from Aeria and log into the game normally.

You will need to uninstall both the Aeria Ignite and Steam versions of the game (add/remove programs and removal of files / folders). After taking care of both versions, you will then need to reinstall your preferred version.
